1.0 DECISION ANALYSIS SUMMARY

Cracks found in many of the double-shell tank (DST) pump and valve pits bring into question the ability of the pits to provide secondary containment and remain in compliance with State and Federal regulations. This study was commissioned to identify viable options for maintaidrestoring secondary zontainment capability in these pits.

The basis for this study is the decision analysis process which identifies the requirements to be met and the desired goals (decision criteria) that each option will be weighed against. A facilitated workshop was convened with individuals knowledgeable of Tank Farms Operations, engineering practices, and safety/environmental requirements. The outcome of this workshop was the validation or identification of the critical requirements, definition of the current problem, identification and weighting of the desired goals, baselining of the current repair methods, and identification of potential alternate solutions. The workshop was followed up with further investigations into the potential solutions that were identified in the workshop and through other efforts. These solutions are identified in the body of this report.

Each of the potential solutions were screened against the list of requirements and only those meeting the requirements were considered viable options. To expand the field of viable options, hybrid concepts that combine the strongest features of different individual approaches were also examined. Several were identified. The decision analysis process then ranked each of the viable options against the weighted decision criteria, which resulted in a recommended solution.

The recommended approach is based upon installing a sprayed on coating system.

Three coatings systems all preliminarily offer acceptable results:

Polyurea Systems, e CeRam-Kote 2000@', and 0

Overall, all are viable. However, more study and testing is recommended to validate vendor claims on physical and chemical compatibility and to provide a uniform basis for comparing the three systems.

2.0 PROBLEM STATEMENT

The principal access to the single and double shell underground storage tanks for waste transfers is through the pump and valve pits located on top or near the tanks. These concrete pits with barrier coatings provide a secondary containment function to prevent waste spills and leaks from reaching the environment. The past practice of no or minimal repairs is no longer acceptable. The degraded or cracked coatings do not provide an impervious waste barrier to the concrete (Washington Administrative

:ode 303-173) and therefore a leakage pathway to the environment is possible. It has been determined hat, over time, components of the waste may diffuse through the concrete and contaminate the adjacent ;oil, In addition to diffusion, cracks in the concrete and barrier coating create potential direct leak paths o the environment. Many of the cracks probably occurred early in the life of the structure because of iormal curing and aging effects in the concrete. Figure 2-1 shows examples of these cracks. Other :auses for cracking are impacts from heavy loads (cover block impact, equipment impacts), separation :racks located at embedment interfaces (thermal and mechanical) (see Figure 2-2), and thermal cycling luring operations. Settling of the soil beneath the concrete is not suspected to be a source of cracking.

The current practices employed to repair pump and valve pit secondary containment defects (cracks in :onCrete and epoxy liner, paint spalling/peeling, etc.) is via manual entry into the pit to effect repairs. b i d e from the dose to workers, the incremental costs to implement these repairs are approximately ;500,000 per pit based on the most recent work in ay pits by ongoing projects (actual cost accrual without site adders).

:xamples of types of Damage in Concrete and their current condition are shown in Table 2.1:

3.0 OBJECTIVE/APPROACH

The objective of this effort was to perform an analysis that identifies and evaluates potential coatings, sealants, and liners that might be suitable for maintaining and restoring secondary containment xipabilities in the included pits. The analysis will address the benefits and drawbacks of each viable Jption regarding performance and cost the analysis will also consider issues of health, safety, mvironment, effects of radiation on the system, and other applicable issues. The report recommends the Jption(s) that represent the most significant improvements above the current practices employed to maintainhestore secondary containment from a system performance, cost, and schedule standpoint. The zurrent methods to re-establish secondary containment are outlined in Appendix A.

The scope of this task will be to maintainhestore secondary containment within the pit structure. The pit structure is defined as including the floor and walls of the pit up to the front edge of the ledge that jupports the cover blocks.

The analysis utilized the Alternative Generation und Analysis Process, HNF-IP-0842, Revision 3.3. The Alternative Generation and Analysis Process is a systematic approach to identify viable options and then use decision analysis techniques to select the preferred alternative that best satisfies the decision criteria.

1.0 REQUIREMENTS, CONSTRAINTS, AND ASSUMPTIONS

1.1 From Washington State Department of Ecology (Ecology), Guidance for Assessing Dangerous Waste Secondary Containment Systems, Pub #95-420

The purpose of secondary containment is to capture and contain releases and spills from primary containment structures, facilitate timely cleanup of these releases and spills, and prevent releases of these wastes to the environment. Secondary containment is widely used for containers and tanks that store, accumulate, and treat dangerous waste.

Note: This document provides guidance for assuring compliance with WAC 173-303-GAC.

Requirements From the July 24,2000, Workshop and Other Sources

The tank pit linerskoatings must meet flammable gas requirements during installation and after it is fully cured.

The SPC system must meet environmental requirements during and following installation.

DECISION CRITERIA

Decision criteria are desirable characteristics, that are “like to have” traits. Unlike requirements, if a product or system does not meet a decision criteria, that product or system is not disqualified from consideration. A product or system that falls short on a decision criteria will receive a lower score than one that performs better in this area.

The decision criteria identified in Table 5-1 resulted from discussions held during the July 24, 2000, workshop. These criteria were utilized in the analysis as the basis for identifying the superior candidate for recommendation. The list on Table 5-1 is a consolidation of 20 desired traits that were identified during the workshop. These 20 traits were then consolidated under 8 decision criteria to form a manageable evaluation matrix. Each of the decision criteria were ranked in importance by using a pair- wise comparison technique. The final ranking established the weight each of the criteria. During the evaluation of the concept options, the decision criteria will be used to identify the superior option.

6.0 ANALYSIS OF ALTERNATIVES

The options identified in this study were researched to understand the performance characteristics of the system along with an assessment of safety, health, environmental characteristicshmpacts, and costs to implement. The decision analysis process is premised upon the basis that all viable options must meet the requirements that have been identified in Section 4.0. Those that do not are discarded from further consideration. In the remaining sections of this report, each option is described as to how this ipplication would be used to maintaidrestore secondary containment capability in the tank pits. If the 3ption does not meet key criteria, a brief discussion will be presented on which criteria are not being met and why the requirement(s) are not met. In some cases, it may appear that requirements are being violated, however discussions found with the specific option will explain why this is not the case. A specific example can be found with the requirement:

“The SPC system shall display an adhesion property to the underlying concrete and previously coated surfaces. Minimum pull-off strength shall be 6,200 Kpa (900 psi).”

Coating systems probably do not require such high adhesion strengths, since the weak link in this system will be the concrete itself. The rule of thumb is that the tensile strength of concrete is 8 percent of the compressive strength. When typically using 3,000 Ib. concrete, the tensile strength will be around 240 psi. Therefore, this study looked for material systems that could ensure that the concrete would fail before the coating could be pulled off the Amercoatd or concrete surface.

Following a screening for compliance to requirements, the viable options were examined from a strengths and weaknesses viewpoint. In other words, no repair system was found to be strong in all areas and perhaps a mix and match approach would identify a superior hybrid system. The combination of the original concepts found to be viable and the hybrid concepts formed the basis for conducting the decision analysis.

6.1 Discussion of Alternatives

The potential candidates fall into two classes: liners and coating systems. In each class, a number of different materials and configurations were examined.

6.1.1 Liner Systems

Stainless steel liners seem to be the most logical solution based upon their inherent durability, long lifetime, and ability to resist chemical attack. The approach for establishing secondary containment is to build a box made from stainless steel. The box would be built in sections that could be lowered into the pit and then assembled in place. The seams would be sealed by metal inert gas welding. Though this approach will meet the requirements spelled out for secondary containment, its downfall resides in the complexity of installation in existing structures and the difficulty in establishing a seal around existing

penetrations. Entry into a pit would be unavoidable, which means that this concept will not score well in the decision criteria matrix.

The use of fiberglass as a liner system would have similar installation considerations that have been mentioned for stainless steel. However, fiberglass is not as durable, its lifetime is more limited than a metal liner, and its fire resistance is less. A particular concern associated with fiberglass would be its susceptibility to impact damage from dropped items and the difficulty in forming seals around existing penetrations. These limitations make fiberglass an inferior choice over metal liners. Fiberglass will not be considered further for secondary containment.

Thermal setting plastics were given cursory consideration as a liner material. Of the candidate materials examined, none were found that could resist sodium hydroxide in the concentrations expected to be present in the pits. Thermal setting plastics are discarded from further consideration.

6.1.2 Coating Systems

On a structurally sound base material, coating systems offer a good option for establishing a secondary containment. However, the pit structures contain numerous cracks and other defects, which may or may not be stable. All coating systems must be installed on a structurally stable base, however, some were able to tolerate small defects in the concrete.

Some types of coatings could also accommodate limited movement at crack interfaces, if bond breakers are applied at the crack. Bond breakers are tapes and/or sub-coatings that are applied over a crack that prevents the coating from adhering in the area immediately adjacent to the edge of a crack. The bond breaker allows the crack movement to be absorbed over a greater area of the coating. The more significant damage to the concrete structure was found in the region located above the cover block ledge (Figure 6-1). This damage tended to be crushing damage that had cracks extending from it. A number of repair methods were documented in American Concrete Institute reports on crack repair. The use of injectable polyurethanes and epoxies appear to be the superior choice for repair and have been used successfully to repair underground pit structures.

None of the coating svstems that were identified were discounted because of toxic or hazardous - , components present during installation. It was assumed that special precautions would be taken through engineered and/or administrative controls in accordance with manufacturers’ recommendations to mitigate any potential problems.

6.1.2.1. Powder Coat Option

Powder coating is often used to protect materials from heat and chemical attack because it forms a smooth, waterproof, and chemical resistant finish that is very durable. The process of powder coating involves spraying a mist of electrostatically charged resin and pigment particles that are then attracted to the base material to be coated. This process depends on the base material being electrostatically grounded so that the charged powder particles will stick to the base and can then be cured into the final

&STORATION OF SECONDARY CONTAJNMEDT N DOUBLE-SHELL TANK PITS - Report No. 990922301-001, Rev. 0


Figure 6-1. Damage Caused By Coverblock.

h i sh . Therefore, the base material must be metal, or have enough metal in it to attract the charged powder particles. Non-metallic base materials, such as concrete and old epoxy paint, would not be able I to be grounded and would therefore not attract the charged powder being sprayed. M e r the spraying i process, the curing process for the powder coat takes place. This requires that the surface to be coated be heated to a minimum of 325 "F, and in most cases the surface must be heated to temperatures exceeding 400 "F. Once applied, this coating would satisfy most of the requirements specified for this project, but since the application process cannot be performed with concrete, it is being rejected from consideration as a possible candidate.

6.1.2.2. Ceramic Coatings

Ceramic coatings are often used for temperature and wear protection in areas where normal coatings cannot be used. The most promising of these products found is CeRam-Kote 2000, a sprayed-on ceramic epoxy coating system that is meant for use in extremely harsh environments

This product meets many, if not all, of the requirements for this project. It can be applied using either an airless or conventional spray system. Having an epoxy base, this coating will most likely cure and be smooth and easily decontaminated, and it will not develop "holidays" during the application or curing process. CeRam-Kote has acceptable elastic properties, which allow it to be stretched at least 30 percent longer than its original length. This indicates CeRam-Kote will be able to bridge existing cracks in the

1 ARES CORWRAlTON

Page 11



concrete base, it will also be able to stretch if more cracking should occur in the future. The WVT and water absorption values for CeRam-Kote are extremely low. The VOC of this product is 1.56 Ib./gal. which is below the 2.9 Ib./gal. requirement. The coating is extremely abrasion resistant and also has a very high tensile strength. The adhesion strength of this product is greater than any other that was found (it exceeded 4,000 psi in pull-off tests). The product is available in a range of colors that includes white, tan, and gray. If cracks should appear in the future, all that need be done is to sand the area surrounding the crack and apply another coat over the affected area. This product is able to withstand extremely high or low temperatures, whether wet or dry, and is compatible with a humidity range of 0-100 percent. The coating is recommended for immersion service with a 70 percent NaOH solution.

This product has uncertainties that must also be mentioned. It is not known how the coating would react to radiation, as it has never been tested in a radioactive environment, however, epoxy compounds typically have excellent resistance to radiation exposure. A filler or backing material may be required to fill larger cracks in the pit walls and floors before the coating is applied. No product literature was provided to show CeRam-Kote will have a operating life of 12 years once installed the basic properties of epoxies, however, suggest that an operating life in excess of 12 years is a reasonable expectation. Also it is not known how much preparation would be needed to make the coating adhere well to a previous coating of h e r c o a t @ epoxy paint. Most likely the surface would need to be thoroughly cleaned and then abraded in some fashion (such as sandblasting, sanding, or etching) before the product could be applied. Despite these uncertainties, this epoxy ceramic product seems to meet requirements and will be considered further.

Aside from this one product, which is an epoxy-ceramic mixture, there are many other types of ceramic coatings. Most are a ceramic enamel type of coating that, once applied, have outstanding heat resistant properties. Such coatings are used in high temperature conditions such as stove pipes, automotive engine and exhaust systems, and space shuttle exteriors. The heat handling capabilities of ceramic coatings of this type far exceed anything that would be encountered in the Hanford tank pits. Aside from this one attribute, these ceramic coatings fail to meet many of the project requirements. Ceramic coatings like this do not meet the water absorption or decontamination requirements, and require high temperatures to cure. Ceramic epoxy coatings are rejected from further consideration.

6.1.2.3.

Sherwin Williams offers an extensive line of products meant for coating both concrete and metal products. Most of their products offer protection from chemical attack, but one product appeared to fit the needs of this project better than all the others. Sherwin Williams@ KemBCure Tank Lining is a two-component hybrid coating comprised of organic thermoset polymer and inorganic silicon oxide. It is meant for immersion and secondary containment use in situations that require resistance to alkalis, corrosion, flexing and stressing, impact, abrasion, and thermal shock.

This product meets or exceeds all the requirements of this project and in addition can be applied with a brush, roller, airless spray, or conventional spray methods. The coating has a gloss finish, which would most likely be easily decontaminated with water. If applied and allowed to cure properly, the product will be free of “holidays,” cracks, and voids. The coating has a 8.2 percent elongation capability that

meets requirements, but may be inadequate to accommodate future expansion and cracks. Further testing is needed. The VOC content is 0.9 lbigal, which is well below the 2.9 1b.igal. allowed for this project. The tensile strength of this product is 13,240 psi and the flexural strength is 13,443 psi. Water absorption was 0.09% after 33 days at 88'F. The adhesion strength of the product was 2,850 psi. The coating is easily repaired for cracks after it has been applied by sanding the cracked area and applying another coat over the sanded area. The product can also withstand conditions of 4 0 'F to 500 "F and is compatible with highly alkaline environments.

This product has several drawbacks. It is only available in two colors, off-white or gray, and not pure white. It may be necessary to use a filler material or other method of covering the existing cracks before the product could be applied. Surface preparation before application would most likely involve some sort of abrading of the surface that the product is to be applied to. The fact that this is a thermoset polymer material means that in order to achieve the fastest curing times, the coating must be heated after application. Otherwise, even with proper ventilation, the coating could take up to 14 days to fully cure. The recommended method of allowing the coating to cure is to heat the applied coating to 180 O F for a minimum of four hours. This could be achieved by placing a heat lamp or other heat source in the pit. After the coating has cured, it will meet or exceed the requirements for this project. This product meets all requirements and will be considered further.

6.1.2.4. Polyurea

Polyurea is a fast set, rapid curing, 100 percent solids, and flexible, two-component polyurea elastomer spray coating material. Polyurea is used by itself or in conjunction with other materials to produce coatings, liners, and resilient surfaces on concrete substrates. The material has an extremely fast gel time that makes it suitable for applications in cold or hot environments. The polyurea produces an extremely tough film at all thicknesses. Single or multiple pass applications produce films from 10 mils to 1,000 mils without appreciable sag or runs. Polyurea is inert, it will not hydrolyze, leach, or contaminate other materials and is relatively moisture and temperature insensitive, allowing application in the most problematic ambient conditions.

Polyurea is a coating material designed specifically for industrial applications receiving constant or intermittent attack from contained materials, subsurface hydrostatic pressure, most corrosive substances, and abrasive action. The material is flexible (200% elongation), accommodating movement of the substrate, yet strong enough to remain intact under adverse conditions. Polyurea is recommended for linedcoating, repair of other films, damaged concrete, or new concrete construction.

Polyurea coatings do not meet the abrasion resistant properties identified in the subject requirements. The requirements are meant to ensure a protective coating that could withstand contact (scraping, etc.) with heavy equipment utilized during all types of operation in and around the pits. Further, it was found that the polyurea exhibits relatively weak resistance to tearicutting damage when solid objects are dropped.

Polyurea coatings do not display the adhesion properties identified in the subject requirements. The requirements are meant to ensure the coating adheres to the existing epoxy and concrete so that the liner

would not "pull-off' and leave the surface unprotected. However, the data suggests that the polyurea will bond to the existing epoxy at a higher value (approximately. 600 psi) than the strength the epoxy to concrete can produce.

The above information is a summary of the product evaluation found in Appendix C.

In addition to the information provided in the product literature, local vendors of polyurea coating products provided demonstrations of material application. The demonstrations simulated surface conditions and configurations that have been observed in the tank pits. Some of the more notable observations during the demonstration was the ability of polyurea to adhere to various surfaces with varying levels of contamination (coated with sugariglycol solution) and the ability to bridge and/or fill racks up to %" in cement blocks without surface preparation or prior crack filling. The vendor added that nails could be fastened to the wall prior to applying the coating to reduce the uncertainties associated with lack of adhesion due to poor surface preparation. This material will be considered further.

Note: A number of vendors were identified as potential suppliers of polyurea. It became apparent that all were using blends of the same basic materials and each could probably supply a product that addressed our needs. Therefore, it is probably appropriate to solicit the best price through the procurement process using a performance specification to ensure adequate performance.

6.1.2.5. Epoxy Coatings

Amercoat'35 1 is manufactured by Ameron, Inc., and is a solventless, high performance epoxy based coating that can be applied with standard airless equipment. It is suitable for use with highly caustic chemicals (such as the tank waste) for coating concrete. A glass flake additive can also be used with the coating to increase film buildup, further reinforce mechanical properties, and lower moisture permeability. Dry film thickness per coat is 8 to 12 mils and 12 to 25 mils with the glass flake additive. The coating is a two part epoxy system where the resin and the cure must be mixed immediately prior to application.

The Ameron epoxy will meet many but not all requirement that have been specified for secondary containment. The coating cures to a gloss finish that is decontaminable based upon prior demonstrations and on site usage of epoxy coatings. Amercoat'351 will meet abrasion specification (41mg. wt. Loss). The adhesion properties at 1,200 psi exceed the tensile strength of the base concrete. There are no VOCs per the vendor's literature. This type of epoxy is compatible with caustics up to 50 percent solutions at 160 "F.

On the negative side, the Amercoatffi351 claims no elongation capability and typically hard finish epoxies do not exhibit elongation ability. Another shortcoming is that this coating may not be able to withstand contact with 200 "F wastes.

Discussions with Ameron Inc. technical representatives indicated that the coating can be applied over Amercoat'33 if it is in good condition (Le., not peeling), without acid etching or priming (Gilbert 1996).

The surface would need to he cleaned and patched and then mechanically abraded before applying the first coat of Amercoat'35 1. A total of three coats, each 8 to 12 mils thick, would be used. If the existing coating is in good condition, another option would be to clean and patch the existing surface and apply one coat of Amerlo~k"~400 (5 to 8 mils thick), which is a self- riming topcoat for use over existing coatings, and then apply two coats of Amercoat"351. Amercoat 1s the baseline and considered representative of typical epoxies.

6.2 Hybrid Approaches

As mentioned earlier, no single concept possessed strengths in all categories covered by the decision criteria. However, some were strong in most areas with significant weaknesses in a few areas and, hence, it appeared reasonable to combine concepts that exploited the strengths of one concept to correct the weakness of another.

In this study, the most promising containment approaches were based upon using stainless steel to form a box within the pit and to use sprayed on coatings such as polyuredepoxies that could he applied directly on the walls and floor. The use of stainless steel met all stated requirements, hut falls short in the area of ease of installation, ALARA, and overall costs (due largely to the difficulty associated with fabricating a metal box within an existing structure in the presence of a radiation field). On the other hand, the sprayed on coating, such as the polyureas and epoxies also had deficiencies. As a class, they most likely require surface preparation (which may he difficult in radiation environment), long-term adhesion is a question, and they were weak in areas where an impact was possible. All other concepts failed to meet minimum requirements for reasons discussed in the previous section.

A range of hybrid options are possible using a combination of the strengths of stainless steel and sprayed on coatings. On one end of the range, a prefabricated stainless steel box is cut into modular sections designed to fit in a particular pit. The sections are lowered into place in sequential order such that the joints make a reasonably tight fit. The joints are then sealed using a polyurea.

Because close fitting joints are difficult to achieve in an existing structure without undue handling (and hence radiation exposure), a less demanding approach focusing upon using stainless steel "wall paper" to provide a prepared surface onto which a coating, such as polyurea, could he applied and considered. The stainless steel "wall paper" would be held in place by nails driven by a powder actuated gun and the floor would he allowed to float. The entire pit would then he sprayed with a coating system, such as polyurea. In this case, the "wall paper" stainless plates would be easily installed, loose fitting plates.

At the other end of the range, stainless steel would only be used for the floor and the floor and walls would be sprayed with a coating system. The metal floor would address the inherent weakness of coating systems to impact and cutting damage. If a nick or cut should occur, it would be unlikely to damage the stainless steel underneath and secondary containment integrity would be maintained. Since the floor receives the most exposure to dropped equipment or even heavy items being set down, a more durable floor system would be appropriate. Further, if the original floor could not be significantly

iecontaminated, a thicker plate could set in place to help reduce the radiation source from the floor. In my event the floor plate would be prepared to optimize coating system adhesion. 6.3 Decision Analysis Process and Results

6.3.1 Secondary Containment Restoration Systems

A decision analysis employing weighted decision criteria was developed to identify the superior option for restoring secondary containment capability in the tank pits. The selected options will meet the requirements identified for this type of containment system. The superior option is that concept that is better than all the others in meeting or exceeding desired goals (called decision criteria) that are in many cases above and beyond the baseline requirements. The decision criteria and their relative weightings were developed during the facilitated workshop conducted July 24,2000. The decision criteria are found in Table 5-1. The members selected to participate in that workshop provided a broad base of tank farm experience that span project management, tank farm engineering, safety, and environmental health.

Each concept is ranked relative to the other concepts to determine which is the best at meeting that particular criteria. The rankings are then multiplied by the weight for that criteria to obtain an overall score. Finally, all the scores for a candidate option are added together to obtain the total score. The highest scoring concept becomes the recommended option.

Based upon the analysis, see Table 6-1, the sprayed on coating system is the recommended system for restoring secondary containment in the tank pits. The use of a sprayed on coating is superior in the area of ALARA considerations because it minimizes the need for pit entry. It also scores well when considering installation characteristics, since the sprayed on coatings, such as polyurea, do not require prior crack repair prior to applying the coating.

The use of a steel plate on the floor is a close second in the scoring. The principle reason is the uncertainty associated with adhesion of sprayed on coatings to surfaces that have minimal preparation. The scoring process assumed that minimal surface preparation was required before the spray coating system was applied; however proper adhesion may be a concern over the design life. The use of a steel plate that has been pre-prepared on the floor will minimize this concern, but the increased effort to install a plate system caused this approach to fall behind a coating-only approach.

6.3.2 Coating Systems

The original intent of this study was to evaluate and select a superior coating system for this application. However, of the three leading candidates identified, none could clearly be identified as a recommended choice.

i decision analysis was unable to distinguish the properties of one system as being favored above the thers. If there were differences between products, it was not clear that they had superior characteristics vith the exception of polyurea’s superior elongation properties and crack filling capabilities. Based ipon product literature and vendor contacts alone, it was not clear that claims of chemical and physical iroperties could be substantiated or that a one-to-one correlation to our conditions was appropriate. lowever, CeRam-Kote and the polyureas appear to offer good crack filling capability along with good :longation properties (polyurea excels in this area). All three will likely provide adequate performance or our intended application. Should only a coating system be pursued, the Polyurea System (subject to :ost confirmation) is the preferred option. However, testing to confirm performance charactertics of all hree candidates is recommended (more to follow).

7.0 ANALYSIS OF LIFE-CYCLE COSTS FOR VIABLE ALTERNATIVES

The components considered in developing life-cycle costs for the recommended options are:

I Original Installation Costs, D Maintenance Costs, D

D Re-installation Costs (if required)

rhe installation costs associated with the hybrid options evaluated by decision analysis in Table 6-1 are ; h o w in summary on Table 7-1. The detailed cost makeup for each option can be found in 4ppendix D. The basis for these estimates is based upon vendor quotes for materials and fabrication ind engineering experience associated with on site construction.

Removal Costs (if required) and

3. SST Plate on Floor with Walls and Flour Coated $42,400' 4. Coating Systems $28,700

*$2K added for pit floor photogrametry

Maintenance costs for all the options is considered to be minimal to none for all the options. However, :here is a risk associated of poor adhesion of the coating system over the 12-year life requirement that nay lead to early failure. In that event, the damaged sections would have to be removed and re- installed. This scenario is not anticipated for Options 1 and 2 where the coating will be applied to surfaces that have been prepared in accordance with vendor recommendations. It is options three and four where the coatings are to be applied over old epoxy surfaces that will receive minimal preparation that poses the concern.

Removal of any of the coating materials poses a unique challenge, because of the difficulty of accessing the pits and the potentially high radiation backgrounds. It is envisioned that a crew equipped with scraper knifes mounted on long poles would remove the defective coating in specific areas (especially around the top edge) and then re-apply a replacement coating. The effort required to accomplish such a task is estimated to require a crew similar in size to the original installation crew for a two-week period, which may represent a $65,000 risk in the future if repair is required. Assuming that a coating failure ioes not occur during the life of the pit, then installation costs would constitute the entire life-cycle cost. [n that case, a straight sprayed on coating would be the least expensive followed by a sprayed coating in combination with a floor plate.

‘.O RISK FACTOR EVALUATION

’here are a number of risks associated with the application of any new coating material in adioactiveicontaminated pits. The hybrid solutions have these same issues where coating systems are sed. In an effort to improve the coating performance from the existing practices, different materials vere examined and compared to identify the best possible material for the required application. As the valuation was performed, different concerns arose specific to the applicatiodperformance of polyurea nd the other recommended sprayed on coatings in the 200 Area pits. Due to the relatively recent xhnology involved with these coatings, vendors do not have significant records identifying product ierformance in ‘‘like’’ applications. The lack of vendor data does not suggest that the material properties d l not be satisfactory, it does, however, introduce a level of uncertainty. The material properties listed elow are identified to have uncertainty associated with their performance. The material properties, the isk associated with those properties, and a possible path forward to mitigate the risks are shown below.

A smooth/easily decontaminated surface: There is no objective evidence or data to ensure a field applied polyurea will produce a smooth, easily decontaminated surface. Small holes and other abrasions appear on the samples of polyurea obtained from the vendor (assumed to have been applied in optimal conditions). A sample of polyurea fixed to a cement block, applied in a similar manner as suggested for the pits, resulted in surface coating pits larger than the samples obtained from the vendor. The effectiveness of future decontamination efforts may be reduced with the presence of these pits.

Path Forward: Establish a test employing application methods and conditions like that planned for the pit to examine the effects of different cure times and component mixtures on surface conditions. The polyurea would be remotely sprayed to simulated pit walls.

A long design life: There is no objective evidence of product lifetime for any of the coating products that were examined. The polyurea products had limited data (approximately eight years) on use of their product in a nuclear application.

Path Forward: Establish tests to expose the material to simulated environmental conditions to document how the material will respond. Of particular concern is exposure to strong caustic solutions and elevated temperatures for potentia!ly prolonged periods.

Good resistance to surface damage: There is concern that polyurea, and to a lesser extent the other coating systems, will not withstand the damage that may occur from operations and maintenance activities in the tank pits.

Path Forward: Conduct tests to evaluate the damage that could be expected from operations and maintenance activities.

$RES Page 19 OWORATION



9.0 RECOMMENDATIONS AND ITEMS REQUIRING FURTHER RESOLUTION

The recommended secondary containment system is a sprayed on coating system.

Three coating systems appear to provide acceptable performance with polyurea systems being superior in the areas of elongation and crack filling capability. However, further testing is recommended to confirm vendor’s performance claims.

It is suggested that the tear-off strength requirement imposed upon coating systems be reduced to match the tensile strength of concrete.

It is suggested that the compatibility of the three coating systems with pit environment, in particular chemical compatibility be verified through testing.

It is suggested that the near-term and long-term adhesion ability of the three coating systems on minimally prepped epoxy, especially around floor penetrations and along top edge be verified.

It is suggested that that the remote application techniques be reviewed to assure they will be successful.

Appendix A Current Practices for Crack and Coating Repair

ARES CORPORATION

Page A-1



Current Practices For Crack And Coating Repair

For cracks (hairline or less in width), chips and spalling: local repair is the current approach. This includes:

e Preparation for coating repair: Wash, apply fixative, remove cover blocks, remove the jumpers and miscellaneous equipment, cover penetration openings, high pressure water wash (whole pit), install shielding (lead blankets), remove dirt and debris, inspect the pit for damage (photos), prep for Amerlock@ 400 (flush and rough up surface) and

e Apply two coats by roller: Poured in then spread around. (This approach poses a problem on future projects; no entry is possible in an pit and entry is discouraged in other pits.)

For cracks greater than hairline, the steps include:

Determine if pit is structurally sound and agree upon repair process;

Prep the structure and coating surfaces for repair (clear out the crack regions);

Inspect the crack damage;

Decide which cracks need to be cut out: Remove paint 2” on each side, clean crack out (water and vacuum), if the crack is less than lmm, coat crack with Amercoat@400, and then fill with NuKlad 114, if the crack is greater than lmm, use saw to create a ,5411. trapezoidal cut into crack for the entire length and then fill with a non-shrink grout);

Allow the grout to cure to manufacturer’s recommendations (Note: Additional costs incurred duc to need to add water for curing and interim checks);

Inspect the repairs;

Prep for Amercoat@ (see previous process steps for 4 m m cracks);

Apply four coats of Amerlock@400 on floors and two on the walls, minimum;

Inspect each coat in pit; and

Reinstall the jumpers and equipment.

Other Past Practices: Repoured the floor, reformed the damaged lips, 236-2 Canyon SS liner repair (puncture fixed with devcon), M Cell Purex (SS liner punctured repaired by welding a patch), poly bladders, pressure grouting at 225-B Cesium Cell.

3 . 0 POLYUREA PRODUCT EVALUATION

The objective of this product evaluation was to assess the characteristics associated with polyurea to letermine its feasibility for use on 200 Area pits, supporting the Waste Feed Delivery System. The naterial was evaluated specifically for use as a secondary confinement barrier for pump pits and valve ,its throughout the 200 Area Tank Farms.

Polyurea is a fast set, rapid curing, IO0 percent solids, and flexible, two-component polyurea elastomer spray coating material. Polyurea is used by itself or in conjunction with other materials to produce Zoatings, liners, and resilient surfaces on concrete substrates. The material has an extremely fast gel ime that makes it suitable for applications in cold or hot environments. The polyurea produces an :xtremely tough film at all thicknesses. Single or multiple pass applications produce films from 10 mils .o 1000 mils without appreciable sag or runs. Polyurea is inert, it will not hydrolyze, leach, or :ontaminate other materials and is relatively moisture and temperature insensitive, allowing application in the most problematic ambient conditions.

Polyurea is a coating material designed specifically for industrial applications receiving constant or intermittent attack from contained materials, subsurface hydrostatic pressure, most corrosive substances, md abrasive action. The material is flexible, accommodating movement of the substrate, yet strong :nough to remain intact under adverse conditions.

Polyurea is recommended for liner/coating, repair of other films, damaged concrete, or new concrete :onstruction. The following are a sample of simple profiles regarding use of the polyurea material in :hemica1 and nuclear applications:

D Great Western Chemical Tank Farm - Two 30,000-gallon tanks were sprayed at 40 mils thick to provide a chemical resistant protective coating/secondary containment. The polyurea material was chosen because it is fast setting, abrasion resistant, bird proof, seamless, and creates a one- piece, well-adhered liner.

SRS Savanna River Site Nuclear Waste Processing Plant - Three square miles of low level contaminated concrete were sprayed (encapsulation of existing coating) to protect the surface from spreading contamination.

Waste Isolation Pilot Plant (WIPP) - Polyurea was used on wash pads (concrete slabs) with heavy traffic to provide a radiological safe environment.

8

To evaluate the applicability/feasibility of the product for the application required, a detailed assessment was performed using requirements derived from WSDOE, Guidance for Assessing Dangerous Waste Secondavy Containment Systems, Pub #95-420 and HNF-SD-W3 14, Rev 1, Requirements Analysis Stud) Tor Special Protective Coating Project Development Specijkation. The following data is developed from a direct correlation between the material and the requirements and specification information Zontained in the aforementioned documents.

Sased on material information supplied by a number of vendors (documentation attached, phone :onversatiom referenced), the following properties of polyurea satisfy requirements contained in WSDOE, Guidance for Assessing Dangerous Waste Secondary Containment Systems, Pub #95-420 and HNF-SD-W3 14, Rev 1, Requirements Analysis Study for Special Protective Coating Project Development Specification.

The polyurea coating system shall develop the ability to resist the development of “holidays” in time.

The polyurea coating system has successfully bridged cracks up to 1.2 mm: These cracks did not propagate through the polyurea coating.

The polyurea coating system provides a tensile strength of 2,500 psi and an elongation of 265 percent. Although these values do not completely meet the requirements referenced, types of polyurea can be mixed with additives to enhance its performance in this area. Based on conversation with NUCOTE vendor - John Meyer, dated July 27,2000.

The polyurea coating system is hydrophobic and therefore absorbs far less water than .05 YO per 24 hrs. The highest WVT rate tested for polyurea was 0.934 gmlm2/24 hr. This coating is compatible with a relative humidity range of 0 to 100 percent

The polyurea coating system has high temperate stability with a service temperature of -60 “F to 300 “F.

The polyurea coating system is generally suitable for continuous contact with substances with PH ranging from 4 to 11. The use at the 200 Area pits will not consist of continuous contact. The polyurea is suitable for application concerning the NAOH environment and the corresponding PH range. Based on conversation with NUCOTE vendor - John Meyer, dated July 27,2000.

Polyurea is 100 percent solids and contains no solvents or VOCs. It has a flame spread rating of “10,” a smoke density rating of “5,” and a National Fire Protection Agency classification of “A,” The polyurea exhibits no unusual fire characteristics. Based on conversation with NUCOTE vendor - John Meyer, dated July 27,2000.

Polyurea can be applied in numerous colors, a number of which suitable for painting over.

Documented evidence exists to show the durability of polyurea is good in applications from 3 to 8 years old. Vendor claims that Polyurea has a design life of about 30 years. Based on conversation with NUCOTE vendor - John Meyer, dated July 27,2000.

Polyurea can be applied over itself to repair damage to the coating. Although this satisfies the requirements, the logistics of using polyurea repeatedly could prove to be difficult.

Polyurea is based on the use of aromatic isocyranate component, and other aromatic species are polymerized into the B component. Aromatics resonate in energized environments including

Page C-3



radionuclides in levels listed in the provided specification. Aromatics have been used in gamma as well as slow and fast neutron environments - polyurea should provide an adequate level of containment with respect to the radionuclides associated with the pump pits and valve pits.

The polyurea coating material was tested concerning the ease of decontamination. The coating material was decontaminated to a maximum DF of 40 (97.5 percent removal) with ambient water. Further washes with ambient and hot decontamination solution increased the maximum DF to 43 (97.7 percent). Note: These values include contamination removal from previous steps.

Polyurea is capable of operating in radiation environments consistent with those found at the Waste Feed Delivery System valve pits and pump pits at the 200 Area. Tests conducted on specific types of polyurea showed the physical properties, when exposed to radiation levels comparable to those in the 200 Area pits, remained suitable for application.

13.

The following polyurea characteristics identified below were determined not to meet the requirements identified in WSDOE, Guidance for Assessing Dangerous Waste Secondary Containment Systems, Pub #95-420 and HNF-SD-W3 14, Rev 1, Requirements Analysis Study for Special Protective Coating Project Development Specification. These characteristics, although outside the “envelope” of compliance, do not necessarily disqualify the coating from consideration. The coating could be used with other methods to mitigate the deficiencies and provide an adequate pit surface liner. The following unsatisfied requirements and corresponding potential mitigation for each, may result in a combination of coating techniques that provide the desired protective liner for the 200 Area valve/pump pits:

1. Polyurea coatings do not meet the abrasion resistant properties identified in subject requirements. The requirements are meant to ensure a protective coating that could withstand contact (scraping, tool dropping, etc.,) with heavy equipment utilized during all types of operation in and around the pits. The potential for contact with the liner would be greatest at the floor (or other horizontal surfaces) as other areas would deflect or resist the force generated by lowered or fallen objects. To mitigate the deficiency, a protective barrier (plate) could be placed on the floor underneath the polyurea coating, therefore minimizing the potential for abrasion in areas most susceptible to damage.

Polyurea coating do not display the adhesion properties identified in subject requirements. The requirements are meant to ensure the coating adheres to the existing epoxy and concrete so that the liner would not “pull-off’ and leave the surface unprotected. Vendor data suggests the polyurea would bond to the existing epoxy at a higher value (approx. 600 psi) than the weathered epoxy would adhere to the concrete. Based on conversation with NUCOTE vendor - John Meyer, dated July 27,2000. Therefore, the polyurea coating would provide an adequate liner as all the epoxy is not anticipated to fail. Furthermore, areas of the concrete without the existing epoxy would be exposed and provide “anchors” for the polyurea, subsequently enhancing the adhesion properties of the liner.

2.

To provide a more conservative design with respect to polyurea adhesion, individual pieces of steel could be prepared, lowered, and attached to the pit to maximize the surface to polyurea bond.

C1.l Surface Preparation

Polyurea general application surface preparations include: cleaning, washing (power wash), application of a primer, and finally a surface coat. These are the recommended preparations with regards to a favorable environment. These processes can be modified, both for coating properties and differing surface configurations. Vendor literature, as well as phone conversation confirmation, exists which documents situations where no priming in necessary, “substrate priming is not required on all substrates.” Based on discussions with an approvedkertified polyurea applicator (Cascade Industries), the application strategy for the 200 Area pits is suggested to be as follows: 1) Power wash at highest pressure allowable, apply a light coat of primer, then apply the polyurea coating.

C1.2 Removal

Polyurea removal is performed by physically cutting (hydraulic cutter, mechanical knife, etc.) the coating from the substrate. Discussions with an approved applicator resulted in data suggesting that an entire surface coating could not be removed without significant effort and time. However, removal of small isolated pieces of the coating, already free from the substrate, could be accomplished remotely (knife on a pole) and in a timely fashion. Regardless of the data received from the vendor, there is some uncertainty associated with removal of the polyurea coating with respect to radioactivekontaminated pits.

Dry Film Thickness: CeRam-Kote 2000 should be applied holiday free at a minimum of 8 mils (200 microns) DFT with a preferred thickness of 10 mils (250 microns) DFT.

Cure Time: A two-pass film of 8-10 mils DFT (200-250 microns) air dries to a dry touch finish within five ( 5 ) hours at 72'F (22.2OC) and dries to a 70% cure in fourteen (14) hours. Cure times lengthen at lower temperatures and shorten at higher temperatures. The coating should be fully cured before placing into service.

Surface Preparation: Bonding strength depends on proper preparation of the surface to be protected for long-teim perfoimaiice of the product. The substrate should be free of oil, grease and saltlchloride contamination. Specifications call for a white metal (NACE 1, SSPC- SP5, Swedish Standards SA-3) finish with a 1-2.5 mil (25 - 62.5 microns) anchor profile. Surface preparation should he no

less than a near white metal (NACE 2, SSPC-SP10, Swedish Standards SA 2 X) finish. Cleanliness is the most important step to produce a coated surface that will perform and last. Call Freecom, Inc. for surface preparation recommendations of materials such as aluminum, brass, plastic, fiberglass and/or concrete.

Mixing Ratio: Four (4) parts of Part A to one (1) part of Part B by volume. Seven (7) paits of Part A to one (1) part of Part B ratio by weight.

Mixing: CeRam-Kote 2000 contains a high loading of ceramic particles which must be placed into full suspension with the epoxy resin prior to application. CeRam-Kote 2000 is packaged in two caps, Part A (base) and Part B (curing agent). Shake Part A (base) with a Cyclone air-powered shaker or mix Part A with an Edsan's Jiffler Mixer until all ceramic powders are suspended in the resin. Time required to place ceramics into suspension varies according to temperature and length of material storage time. At 72'F (22.2"C), generally a four (4) to six (6) minute shake will place the ceramic powders into suspension. Regardless of time needed, shake all ceramic material into suspension prior to proceeding. Failure to properly mix will keep CeRam-Kote 2000 from performing or curing properly. Check the can to assure all solids are in suspension prior to proceeding to the mixing step.

Combine Part A (base) and Part B (curing agent) and shake again until both parts are thoroughly mixed. Shaking time is temperature dependent, but a two (2) to four (4) minute shake at 72°F (22.2T) should thoroughly mix the components. However, caution must be used to prevent heat buildup. No induction time is needed before application.

Pot Life & Shelf Life: Pot life for CeRam-Kote 2000 at 72'F (22.2"C) is approximately six (6) to eight (8) hours. Colder temperatures will increase the pot life and warmer temperatures will decrease the pot life. Keep cans out of direct sunlight to prevent heat buildup. CeRam-Kote 2000 has an indefinite shelf life. Prefened storageiusage is a dry enclosed area under 85°F (29°C) /used within two (2) years. However, if stored more than two years above 85°F (29"C), call Freecom Technical Support prior to use.

Thinning: Use MEK, Isopropanol (99%), or Acetone for any viscosity. Never thin CeRam-Kote 2000 more than 5% by volume. Thinning dilutes the high solids of CeRam-Kote 2000, creates excessive overspray and may affect the performance of the coating.

Application: Spray apply for best results using conventional, airless, HVLP or cup gun. The air source must be dry. The compressed air source should be outfitted with air dryers as needed to supply moisture-free air. Use pressure feed equipment such as high volume, low pressure equipment or Binks 2001 spray equipment with a 563CVT needle, 63CVT fluid nozzle and 63PB air nozzle. Airless: use reversible carbide tip with orifice size of 0.019-0.021 inches. If applying with roller, use short nap, such as %" (.244 mm).

After thoroughly shaking CeRam-Kote 2000, strain it with a standard paint strainer and pour CeRam-Kote 2000 into the spray equipment.

Apply a first pass of five (5) to six (6) mils (125-150 microns) WFT and allow sufficient time for solvent to flash off. At 72'F (22,2OC), 30-40 minutes is sufficient. Apply a second pass of five (5) to six (6) mils (100 - 125 microns) for a total DFT of eight (8) to ten (10) mils (200-250 microns). Cure time is temperature dependent.

Apply additional mils without incurring runs or sags if the finished product requires thicker coverage. Whenever possible, apply second coat in a cross-coat method.

Climate: Use CeRam-Kote 2000 only if the substrate temperature and ambient air temperature is above 40°F (4.4"C). No coating should be permitted when substrate is wet from rain or dew, when surfaces are less than 5°F (3OC) above the dew point and holding or when relative humidity is greater than 85%. Moisture will inhibit the catalyst reaction and CeRam-Kote 2000 will not cure or perform properly.

Holiday Detection: CeRam-Kote 2000 is classified as a thin-film coating and should be tested for defects and holidays using a 67% volt, wet sponge spark detector set at 80,000 ohms resistance, such as a Tinker and Rasor model M-1

CeRam-Kote 2000 Product Data Sheet Page 3 of 3 RPP-6855, Rev. 0

Repairs: If application of the coating is less than seventy-two (72) hours old and has not been exposed to contamination, repair by wiping with MEK and then re-apply CeRam-Kote 2000. If contaminated or more than 72 hours old, first sand with appropriate p i t sandpaper, then repeat repair process.

Cleanup: Purge and clean spray equipment within thirty (30) minutes of the final spray. Flush equipment with MEK until solvent sprays clear. Disassemble and clean equipment to manufacturer’s recommendations. Material left in spray equipment could solidify and damage equipment. Use precautionary measure applicable to any catalyzed material.

Safety: See individual product label for safety and health data. A Material Safety Data Sheet is available upon request.

SURFACE PREPARATiON

Surface must be clean, dly. and in sound condition. Remove all oil, dust, grease, dirt, loose rust, and other foreign material to ensure adequate adhesion. Iron B Steel (Immersion service): Remove all oil and grease from surface by Solvent Cleaning per SSPC-SP1. Minimum surface preparation is White Metal Blast Cleaning per SSPC-SP5. Blast clean all surfaces using a sharp, angular abrasive for optimum surface profile (34 mils). Remove all weld spatter and round all sharp edges by grind- ing to a minimum 1/4' radius. Prime any bare steel the same day as it is cleaned. Stainless Steel (immersion service): Remove all oil and grease from surface by Solvent Cleaning per SSPC-SPI. Minimum surface preparation is White Metal Blast Cieaning per SSPC-SP5. Blast clean all surfaces using asharp. angularabrasiveforoptimumsurface profile (34mils). Remove all weld spatter and round all sharp edges by grind- ing to a minimum 114' radius. Prime any bare steel the same day as it is cleaned. Pourad Concrete New Surfaces must be clean, dly, sound and offer sufficient profile to achieve adequate adhesion. Minimum cure is 28 days at 75°F. Remove ail form release agents, curing compounds, salts, efflorescence, laitance, and other foreign matter by sandblasting, shotblasting, mechanical scarification, or suitable chemical means. Follow with 16% muriatic acid etch at the rate of 75 sq Wgal. Refer to ASTM D4260. Rinse thoroughly to achieve a final pH between 6.0 and 10.0. Allow to dry thoroughly prior to coating. Old Surface preparation is done in much the same manner as new concrete, however, if the concrete is contaminated with oils, grease, chemicals, etc.. they must be removed by cleaning with a strong detergent. Refer to ASTM D4258. Form release agents, hardeners, etc. must be removed by sandblasting, shotblasting, mechanical scarification, or suitable chemical means. If surface deterioration presents an unacceptably rough surface, Kem Cati-Coat Epoxy Surfacer is recommended to patch and resurface damaged concrete. Fill all cracks, voids and bugholes with Corobond Crack Filler. Alwaysfollow the ASTM methods listed below: ASTM D4258 Standard Practice for Cleaning Concrete. ASTM D4259 Standard Practice for Abrading Concrete. ASTM D4260 Standard Practice for Etching Concrete. ASTM D4263 Plastic Sheet Method for Checking Moisture in Concrete. Immersion Service: In addition to the above surface preparation, Brush Blasting of the concrete surface is required.

Subject:

Dear Ms. Bush:

Proiect Introduction

This letter is a fulfillment of the request of Specialty Products (Purchase Order 253 1).

Technical Introduction

The selected test option calls for drying a contamination solution unto a prepared (coated) sample. The sample is then washed with a sequential series of washes with 1) water, 2) ambient temperature decontamination solution and finally 3) hot decontamination solution.

Method

The Test was conducted in accordance with ASTM D42.56-89' with minor changes noted below in the "Results" section. Laboratory ~ c k : xcd results %eit L ~ X I L & ~ iii aiduuiaiury i<oi&uuk or on GammaVision TM data printouts.

Results

The total decontamination factor @F) is the ratio of the original activity to the activity after treatment. Note that these values include contamination removal by the previous steps. The decontamination factors are given for each of 137Cs, 6oCo and Total Count. 6oCo is typical of a transition metal ion in that it tends to be less soluble in water than an alkali metal like 137Cs. The Total Count is essentially the average of the two, since the initial activity of the two radionuclides was essentially the same and the only activities on the sample are 137Cs and 6oCo.

The used water wash was tested to help c o n f m the loss of radioactivity from the samples and did c o n f i i the loss of both I3’Cs and 6oC~. Due to the dilution factor in the wash water and the decreasing amount of activity on the samples, only the water wash was tested.

The samples are “decontaminated” by dipping them in stining water or decon solution. After the water wash the samples were lightly tissue-wiped on the uncontaminated side after rinsing the uncontaminated side (per the ASTM method). No major contamination was detected.

It was noted in the preparation of the ambient decon solution that the makeup water was closer to 15 “C than the method-required 24 2 3°C. The water solution (for the water wash) had not been checked for temperature, as the ambient air temperature was close to 24 “C. This may have caused the slightly low values for I3’Cs removal for the water wash.

Although the ASTM method calls for this report to include “Procedures and conditions relating to the test specimen preparation”, since PN Services did not prepare the samples, this information is not included.

The specimens were stained brown on the areas where the last of the contaminating solution had dried. The stains were in a doughnut shaped pattern. The brown color could indicate attack by un- neutralized nitric acid, but the samples clearly had white crystalline solids on them after the contamination solution had dried (before the water wash), which would indicate that neutralization by sodium hydroxide had occurred.

The immersed portions of the samples were slightly darker than the un-immersed part, after the ambient decontamination solution immersion.

Changes from the letter of the ASTM procedure were made for a number of reasons. Due to the size of the steel plate sample, the decontamination was done in a 2L glass crystallizing dish (vs the 600 mL polyethylene beaker of step 10.2.1). Both samples were decontaminated in the same bath. Section 9.2 states that I ‘ . . .immediately adjust to pH 4 with 8M ammonium hydroxide (NaOH).” The correct chemical formula for ammonium hydroxide is N h O H . We were left to make a &+-- ~ \ ~ i ~ t *irh?thw tn i i c ~ NnnFT nr “.OH Since Hanford snliitinnq are likelv to contain NaOH - sodium hydroxide, this was used as the neutralizing agent. Also, measuring the pH of a 0.2 mL solution was not possible so the solution was neutralized with an equivalent amount of 8 M NaOH solution.

Discussion and Hwotheses

The differences between the plate and block samples could be accounted for by: 1) the higher ratio of front (unrinsedunwiped) area to wipe-able area for the plate, 2) the block was more easily positioned in the gamma detector than the plate, which was just slightly wider than the shelf jig. The higher ratio of front area to wiped area for the plate may have had the effect of making the front surface available for recontamination. Poiitioning the plate in the gamma counter shelf jig was difficult. If the initial (freshly contaminated) count were done with the plate tilted slightly further away from the detector than the other counts, the decontamination ratio would be lowered due to the lowered initial count.

.I C-30

RF'P-6855, Rev. 0

- A possible reason for the differences between I3'Cs and %o is that since the solution was neutralized, the %o may have been in an insoluble hydroxide compound, and therefore not as subject to binding with the coating. A pH neutral solution of Cs still has ionic Cs in it, which would be attracted to ion exchange sites.

Conclusions

The coating material w% decontaminated to a minimum decontamination factor @F) of 21.6 (95.4 % removal) with ambient water. Further washes with ambient and hot decontamination solution increased the minimum DF to 22.4 (95.5 ?& removal).

Tne coating material was decontaminated to a maximum decontamination factor of 40 (97.5% removal) with ambient water. Further washes with ambient and hot decontamination solution increased the maximum DF to 43 (97.7 % removal).

Reference P I : Contained material: Container:

Sodium Chlorate - ph 13 Tile Lined Steel Tank and Mild Steel Tank Intzrior Roof

The initial installation was undertaken at Weyerhaeuser (then: Avenor) Dryde$ Ontario pulp plant in June 1998. The completed installation has been in constant senice since that time. The tank is inspected on a semi-annual basis. Four such inspections have taken place to date. The system is performing without flaw or repair. The owner has subsequently released several more tile line steel tanks and stainless steel tanks for lining.

Reference #2: Contained mataial: .:.

White Liquor (Sodium Chlorate) - pH 12 Steel White Liquor Settling Tank Container:

This installation occurred at Kimberly Clark Winslow, ME in August 1998. .:. Reference #3: Contained material: Bleaching Chemicals - pH 12

Container: Concrete Holding Tank

This installation at Repap, Mirimichi, New Bmnswick occurred in August 1998.

The above installations are in active service and are all primary containment for the mentioned high pH materials. VersaFk reconunends use of its polyurea materials in these types of circumstances on a continuing basis. We have warranted many such msdations at the request ofthe various owners.

TOXICOLOGICAL DATA

Polymeric MDI: Oral LDSO (rat) > 5.00 mgkg Dermal LDSO (rabbit) > 5.00 makg Inhalation LCSO (rat) - 490 mg/m3/4H (respirable aerosol)

POTENTIAL HEALTH EFFECTS:

Inhalation: This product is a respiratory and potential respiratory sensitizer. Repeated inhalation of vapor or aerosol at levels above the occupational exposure limit could cause respiratory sensitization. Symptoms may include imtation to the cycs. nose. throat and lungs. possiblycombined \&ith dryness ofthe throat. tightness ofchest and difficulty in breathing. The nnsa ofthe respiratorysymptoms may be delayed for several hours after exposure. A hyperreactive response to even minimal concenrrations of MDI may develop in sensitized persons.

Skin Contact: Mcderse irritant. Repeated andior prolonged conuct may cause skin sensitization. Animal rmdies have shoun that rcspiratory sensitization can be induced by skin conun with known respiratory sensitizers including diisocyanatcs. Thew resuits emphasize the need for protcnive clothing including gloves to be worn at all times when handling these chemicals or in maintenance work.

Eye Contact: The aerosol. vapor or liquid w i l l irritate human eyes following contact.
